DX52D+ZM
DX52D+ZM steel coil is a zinc-aluminum-magnesium coated steel product manufactured according to EN 10346 standards. It combines a highly formable DX52D cold-forming steel substrate with an advanced ZM (Zinc-Magnesium-Aluminum) coating, offering excellent corrosion resistance and processing performance.
Aluminum-Magnesium-Zinc coated steel is a new type of highly corrosion-resistant coated steel sheet with a coating composition consisting of zinc as the main substrate in combination with aluminum (about 11%), magnesium (about 3%) and a trace amount of silicon.Adding Al, Mg, and Si to it, the composite effect of these added elements improves corrosion resistance.Compared with hot-dip galvanized steel sheet and hot-dip galvanized-5% aluminium alloy steel sheet, it has less adhesion but equal corrosion resistance. In addition, it can be used instead of stainless steel or aluminium sheet because of its excellent red rust resistance.

Why Choose ZM-Coated Steel for Solar Mounting Systems?
1. Longer Service Life
The zinc-aluminum-magnesium coating provides outstanding protection against corrosion, making it suitable for harsh outdoor environments and coastal areas.
2. Lower Maintenance Costs
The self-healing effect at cut edges helps reduce rust formation and minimizes maintenance requirements throughout the project lifecycle.
3. Cost-Effective Solution
Compared with traditional hot-dip galvanized structures, ZM-coated solar mounting systems can achieve similar or even better corrosion performance while reducing overall manufacturing and installation costs.
5. Faster Project Delivery
By sourcing both raw materials and finished mounting components from a single supplier, customers can simplify their supply chain and accelerate project execution.
